I'm slightly confused about this software. I'm currently a design student and apparently I need the CS5 software. If I purchase the student edition, am I not allowed to use it once I'm no longer a student? Is there a difference between the student edition and the commercial edition? And if I can still use the student edition after I graduate, can I use it for work? Please kindly clarify.

For the record, Manish_1988's original reply stated that the software cannot be used for commercial work. I see that's been edited out, but for those only getting emails please note this is incorrect. As long as you're eligible to buy the software you can use it for commercial work.
